acquired - senile calcification, rheumatic fever
aortic stenosis: differential for an systolic murmur
HOCM
VSD
aortic sclerosis
flow murmur
coarctation of the aorta
aortic stenosis: examination findings
ejection systolic murmur heart loudest in aortic area and radiating to the carotids
soft S2
slow rising pulse
narrow pulse pressure
displaced apex
aortic stenosis: presenting features
asymptomatic
dyspnoea
syncope
aortic stenosis: management
monitoring
medical management of HF
if severe or symptomatic, TAVR or surgery
aortic stenosis: investigations
Echo
ECG
CXR
mitral stenosis: presenting features
asymptomatic
dyspnoea
haemoptysis
malar flush
palpitations (AF)
mitral stenosis: causes
acquired - rheumatic fever
mitral stenosis: examination findings
Mid-diastolic murmur heard loudest at the apex, reinforced by leaning on side in expiration
loud S1
malar flush
irregular pulse (due to AF)
evidence of pulmonary hypertension (P mitrale)
signs of rheumatic fever (rash, nodules etc.)
mitral stenosis: differential for diastolic murmur
Austin-Flint murmur
Large mitral valve leaflet from endocarditis or myxoma (late diastolic murmur with mitral ‘plop’)
mitral stenosis: investigations
Echo
ECG
CXR
mitral stenosis: management
medical management of AF and heart failure
if severe or symptomatic, mitral valvuloplasty or surgery
mitral stenosis: complications
pulmonary HTN
AF
Duke’s Major Criteria for Endocarditis
- typical organism found on two blood cultures
- evidence of endocardial involvement (Echo)
2 = diagnostic
Duke’s Minor Criteria for Endocarditis
- fever >38deg
- suggestive features on echo
- predisposition (e.g. prosthetic valve, IVDU)
- embolic phenomena (Janeway Lesions, clubbing, splinter haemorrhages)
- immunological phenomenon (Roth spots, Osler nodes, vasculitis)
- atypical organisms on blood culture
5 or 1 major + 3 minor = diagnostic
Infective endocarditis: empiric antibiotics for native valve disease
amoxicillin + gentamicin
Duckett Jones Major Criteria for Rheumatoid Fever
- arthritis
- (peri)carditis
- Sydenham’s chorea
- Rheumatoid nodules
- Erythema marginatum
2 = diagnostic
Duckett Jones Minor Criteria for Rheumatoid Fever
- fever
- arthralgia (not arthritis)
- recent Strep infection (culture or raised ASOT)
- raised inflammatory markers
- ECG changes (QT or PR prolongation)
1 major + 2 minor = diagnostic
Rheumatoid Fever: management
- bed rest
- high dose aspirin
- penicillin (benzylpenicillin IV STAT + phenoxymethylpenicillin PO 10 days)
mitral regurgitation: causes
congenital - connective tissue disease
acquired - degeneration/prolapse, infective endocarditis, rheumatic fever, MI (papillary muscle rupture), dilated cardiomyopathy (annular dilatation), infiltrative (amyloid)
mitral regurgitation: examination findings
pan systolic murmur heard loudest at the apex and radiating to the axilla
soft S1, split S2
pulmonary oedema
LV dilatation
signs of endocarditis
mitral regurgitation: presenting features
asymptomatic
fatigue
dyspnoea
oedema
palpitations (AF)
mitral regurgitation: investigations
Echo
ECG
CXR
mitral regurgitation: management
medical management of AF and HF
for severe for symptomatic disease, surgical repair (occasionally consider mitral clip)
aortic regurgitation: causes
congenital - bicuspid valve
acquired - infective endocarditis, rheumatic fever, aortic root dissection, aortitis (syphillis, AS)
aortic regurgitation: presenting features
asymptomatic
dyspnoea, worse on lying flat
aortic regurgitation: examination findings
early diastolic murmur heart at LLSE, reinforced by leaning forward in expiration
+/- Austin Flint Murmur
collapsing / waterhammer pulse
wide pulse pressure
hyperkinetic, displaced apex beat
S3
Quincke’s sign (nailbed capillary pulsation)
De Musset’s sign (head bobbing)
aortic regurgitation: investigations
Echo
ECG
CXR
aortic regurgitation: management
monitoring
medical management of heart failure
for severe or symptomatic disease, aortic valve replacement
tricuspid regurgitation: causes
congenital - Ebstein’s Anomaly
acquired - pulmonary HTN (e.g. COPD), rheumatic fever, infective endocarditis (IVDU), carcinoid
tricuspid regurgitation: presenting features
asymptomatic
fatigue
dyspnoea
palpitations (AF)
epigastric pain, jaundice, ascites
